To all whom, ft may concern:

Be it known that l, JOHN SANDS, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented a new and useful W'ater-Motor, of which the following is a specification.

My invention relates to a Water-motor, including a turbine wheel of the overshot type, with a governor mechanism controlled by variations ot' resistance offered to the wheel by changes of load carried by the driven shaft; and the objects in view are to provide animproved construction of Wheel-buckets whereby the force of the motive liquid is applied at its maximum efficiency for the economization ot' such liquid and to provide governing mechanism whereby the direction of application of the stream ot' motive liquid may be changed to vary the degree of efciency thereof or maybe wholly withdrawn owing to a sudden reduction ot' resistance or load to allow the speed of rotation of the wheel to decrease to a normal standard.

Further objects and advantages of this in'- vention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings, Figure 1 is a side View, partly broken away, of a motor constructed in accordance with my invention. Fig. 2 is a front view with the casing partly broken away. Fig. is a rear view with portions of the casing and supplypipe or conductor broken away. Fig. d is a detail view in perspective of the latch for securing the nozzle of the liquid-con d uctorin its inoperative position, showi ng the contiguous parts with which said latch cooperates. Fig. 5 is a similar View of the retaining-lever and trip mechanism, including means whereby the retaininglever is locked in its normal position. Fig. 6 is asimilar View of the returning-leveraud repressing-iinger. Fig. 7 is a similar View of the pressure-pan and contiguous portion of the tilting lover.

Similar numerals otreference indicate corresponding parts in all the figures of the drawings.

ln a casing l, which maybe ot any suitable construction, is mounted an overshot turbine wheel 2, having a driven shaft 3, a motive liquid for operating the wheel being applied by means of a pipe or conductor 4, having a nozzle 5, which is flexibly connected, as at 6, to the fixed portionbf the conductor, and the latter being fitted with a controlling-valve 7. Any suitable means, as a hanger 8, may be employed for supporting the extremity of the fixed or body portion of the conveyer, while the nozzle is held in the desired relative position to discharge liquid, as may be required by the differences of operation, by a link 9, pivotally connected to a band 10, encircling the nozzle atan intermediate point, said link extending through a box l1, in which is arranged a supporting-spring 12, acting' against a disk 13, fixed to the link.

The periphery of the Wheel consists of a rim 14, from t-he side edges ot' which rise flanges or walls 15 and 16, connected by transverse wings or partitions 17, by which the interval between the flanges or side walls isV divided to form buckets for the reception ot' the liquid discharged by the con veyer. These wings or partitions are disposed radially or perpendicular to the tangents ot' the circumference of the wheel, at the several points of such circumference which are intersected by the wings; but the latter are disposed angnlarly with relation to the side walls or across the face of the wheel diagonally, the preferable angle being about seventy-two degrees. The eitect of this angularordiagonal disposition of the wings is that when a stream of motive liquid is discharged upon a wing when the latter is approximately at an angle of forty-live degrees to ahorizontal plane, as shown in Fig. 1, the liquid coming in contact with the upper end of the wing contiguous to the ianges or walls 16 is deflected by the lateral inclination of the sur face toward the flange or wall 15. Coming in contact with the wall 15 it is deiiected rearwardly or inwardly by reason of the inward depression of the wing until it strikes the rim 14., and from thence it is thrown forwardly or outwardly by reason of centrifugal force and the then outward depression of the wing and is concentrated at a point approximately one-third ot the length of the wing from the wall 15 toward the Wall 1li. Thus the blades have a lateral inclination which is permanent and a radial inclination which IOO is variable, in that on the descending or operative side of the wheel a blade is first inclined downwardly and inwardl-y, and as the motion continues said inclination becomes less, until the blade is radially horizontal, after which it declines outwardly to discharge the water after it has accomplished its function. Hence as the water is applied To a 'blade when its radial depression is inward said water is caused to flow inward,I

While at the same time it has a lateral movement, due to the lateral inclination of the blade; but bythe time the water has reached the rim and is checked in its inward movement the blade has passed its radially-horizontal position and begins to decline outwardly, and hence causes the water to liow toward the outer edge of the blade, said outward movement being acceleratedby centrifugal force. The permanent lateral inclination of the blade and the variable radial inclination thereof due to the rotation of the wheel cause a whirling motion of the water, which concentrates it in an approximately solid stream for discharge. Itis obvious that when the wheel is revolving at the speed of maximum efliciency the velocity of the water is practically lost in its impact with a wing and becomes dead g but gravity, as-` sisted by any velocity remaining in the water, is sufficient to cause the lateral deflection of the water toward the flange l5, and hence initiate the whirling motion above described. Obviously this whirling motion will be lost when the wheel is revolving at a speed less than that of maximum efficiency, as when overloaded, by reason of the fact that the water will have a tendency to rebound, andl thus come in contact with the forward side of the succeeding blade or Wing; but even under these circumstances the lateral inclination of the blade or wing and the inwardlydepressed position which the blade occupies' when encountered by the water will tend to cause a del'lection laterally and inwardly to` a sufficient extent to concentrate at least a portion of the water at such a point as to be discharged upon an object, which is herein-` after described as provided for its reception. Arranged in the paths of these concentrated streams of motive liquid as they issue from the buckets of the wheel is a pressu rc-plate, preferably constructed in the form of a pan or cup 18, carried by a tilting lever 19, which is provided with a coun terbalancing-weighl 20,havi 1; but a reduction of load, as applied to the driven shaft and causing a corresponding increasein the rate of rotation of the wheel, will cause' the' motive liquid to be discharged from the buckets with greater force upon the pres'- sure pan or cup and by depressing the latter will cause the elevation of the weighted arm of the tiltinglever against the resistance offered bythecounterbalancing-weight20. Said long arm of the tilting lever is connected by a rod 23 and an intermediate lever 24 with the link 9, by which the nozzle of the conductor is supported, and hence any elevation of the long 'arm of the tilting lever will cause an upward deection of the discharge end of the nozzle and a proportionate reduction in the force of impact of the motive liquid upon the wings of the wheel. In order that the normal point of impact of the motive liquid may be adjusted to vary the normal speed of the wheel, (as it will be obvious that with the point of impact located near the outer edge of a wing a very slight deflection of the nozzle from its normal position will cause the stream of motive liquid discharged thereby to be divided on the edge of the wing, and thus lose a `portion of its efficiency, whereas if the point of impact is remote from the outer edge of the wing a greater deflection of the nozzle will be necessary in order to reduce the efficiency of the motive liquid,) the connecting-rod 23 is made of extensible construction, the connected sections 23 and 23b thereof being connected by a threaded joint 25 and the rotatable section 23iL being Aprovided at its upper end with a milled nut 2o' to facilitate the adjustment thereof. A swivel connection 27 is employed between the upper extremity of the section 23 and the ear 28, by which a pivotal attachment of the rod 23 to the intermediate lever 24 is secured. In a guide 29, through lwhich the connecting-rod 23 extends, is arranged a binding-screw 30, which when adadjusted to impinge against the connectingrod serves to lock the latter against longitudinal movement, and hence secure the tilting pan or cup in a xed position.

It is obvious that when the nozzle of the conductor is deflected slightly, as above indicated, to compensate for a proportionate decrease of load the resulting reduction of the rate of rotation, due to the decrease in the efliciency of application of the motive liquid to the wheel, will cause the parts to resume their normal posirions,and thusinsure :the subsequent application of the motive liquid to the wheel at the maxim um efliciency,

IIC

shifting weight 2O to move forwardly or toward the fulcrum of the tilting` lever, and thereby reducing the efficiency of the counterbalancing-weight and causing a still furtherdeiiection of the nozzle, which will bring it into registration with an inlet-spout 3l, carried by a piston-cylinder 32, said spout having a stop-ear 33, which limits the upward deflection ot' the nozzle and causes the stream of motive liquid to be projected into the cylinder to depress a piston 34 arranged therein. This depression of the piston by reason of the piston-rod 35 and a link 36 is communicated to one arm of a rocking lever 37, which may be fulcrumed at an intermediate point upon a hanger or bracket 33, supported by the casing. To the other extremity of this rocking lever is pivotally connected a pitman 39, of which the lower extremity has connection, through intermediate elements, with a triplever 40, arranged in operative relation with a cam 4l on a yielding preferably springmetai latch 42,supported by a suitable bracket 43. The function of this latch is to secure in its normal position a retaining-lever 44, of which one end is iitted with a segmental slotted extension 45, :forming a guide for a lateral pin 41,5 on the lower extremity of the pitman 39, said latch carrying a pin 47 to engage an opening 48, as shown in Fig. l.

The connection between the pitman 39 and the tri p-lever 40 includes an arm 49,fulcrum ed at one end upon the bracket 43 and having the contiguous end of the trip-lever connected to an intermediate point thereof, and a link 50, pivotally connected at one end to an enlargement 51 on the extremity of the pit-man 39 and attached to the free end of the connecting-lever 4i), said link 50 being provided with spaced nuts 52, arranged, respectively, above and below the extremity of the lever 49 and adapted to be adj usted to lengthen or shorten the link, and hence vary the throw of the trip-lever, which is necessary in order to bring it in operative contact with the cam 41.

The retaining-lever is fulcrumed upon a bracket 53 and is connect-ed at the extremity opposite to the slotted segment with a returning-lever 54 by means of intermediate elements, including a rocking lever 55 and toggle-jointed links 5G and 57. The link 56 comprises members 5Ga and 56", terminally mounted, respectively, upon the returninglever 54 and the rocking lever 55 and connected at their contiguous extremities by a knuckle 50c, stop-hinges being employed at the joints between l he knuckle and said link members to limit the relative deflection of said parts in both directions. The link 57 comprises members 57L and 57b and a knuckle 57C, the member 57b having a stop-pin 58, operating in a segmental slot 59 in the knuckle to limit the relative deiiection of the members ot' the link.

The retnming-lever 54 is of bent or bowed construction and is terminally provided with a slotted link GO, engaging a guide-pin 61 on the tilting lever 19, and is also provided at the same extremity with an actuating-weight (32, of which the tendency is to depress the free end of the returning-lever from the normal position (illustrated in Fig. l.) and which operates to so depress the same when released bythe disengagement ot` the latch 42 from the retaininglever. \Vhen, therefore, the piston 34 is depressed by the motive liquid introduced into the cylinder 32, thus elevating the pitman 3i), the trip-lever 40 comes in contact with the cam 4l and disengages the latch 42 from the retaining-lever 44, which in its normal position maintains the returning-lever 54 in its normal or elevated position. (Illustrated in Figi.) VVhenthe retaining-lever is released, the returning-lever is depressed by its actuating-weight 62 until the upper extremity of the slot in the link comes in contact with the stop-pin 6l and depresses the long arm of the tilting lever to elevate the pressure pan or cup to its normal position. The returning-lever also preferably carries a finger (i3, which as the said lever is depressed strikes the traveler 2l and starts it rearwardly toward the stop 22 at the extremity ot` the tilting lever. Obviously the return of the tilting lever t-o its normal position correspondingly returns the nozzle 5 to its operative position and the motive liquid is again applied to the buckets of the wheel.

I have found in practice that it is desirable to employ locking devices in connect-ion with the rocking lever 37 to temporarily retain the latter in the position to which it has been moved by the depression of the piston 34, and hence in the drawings I have shown a latch 64, weighted, as at G5, and having a shoulder G6 to engage over the depressed arm of the lever 37 when it has reached said adjusted position, and in connection with the cylinder 32 I employ an auxiliary chamber G7, contain ing a plunger 68, of which the rod tif) is connected, by means of a link 70, with a releasing-arm 7l. Then the piston 34 reaches thc limit ot its downstroke, it exposes a port 72, which is in communication with the auxiliary chamber below the plane of the plunger G8, whereby at the moment that the rocking lever 37 is locked in itsdepressed position by the latch (34 the motive agent is communicated from the cylinder 32 to the auxiliary chamber below the plane of the plunger GS, thereby raising said plunger, and hence the releasing-arm 7l, to bring the latter into contact with a trip 73, formed by an upward extension of the latch, and thereby disengage said latch from the rocking lever 37. Hence after the returning-lever has been depressed to restore the pressure pan or cup to its normal operative position, and thereby return the nozzle into such a position as to Ireject motive liquid upon the wings ot' the wheel, the rocking lever 37 is released for return to its normal position by a return-weight 74, carried by the pitinan 3U. The depression of the IDO IIO

pitman 39 causes a corresponding depression of the end of the retaining-lever which carries the slotted segment 45, and hence reengagement of the latch-spring 4t2 therewith to secure the parts in the relative positions indicated in Fig. l. Obviously the return of the rocking lever 37 to its normal position is accompanied by the rising of the piston 34: and the discharge of the liquid in the cylinder above said piston through the spout 8l, while the liquid in the chamber 67 beneath the plunger 68 escapes through the port 72 and the opening 75 in the bottom of the cylinder 32.

An outlet 76 at the bottom of the casing provides for the escape of the motive liquid which has performed its function in cont-act with the wheel.

Various changes in the form, proportion, and the minor details of construction may be resorted to Without departing from the spirit or sacrificing any of the advantages of this invention.
